Useful Devices for Audio Weblogging?

Henri Poole asks: "I'm advising the Kucinich Presidential campaign on technology and we are looking for an audio webblogging solution. Kucinich's assistant plans to log his own travels and would prefer to do so via voice. We're looking for a device with the following functionality: phone, web, email, audio, and calendar. Verizon is the preferred (but not essential) service and they are advising that we buy Samsung or Kyocera equipment. We'd prefer a free software solution...any sage advice?"
